The Battle of Wassaw Sound (or the Capture of the CSS Atlanta) was an American Civil War naval battle between the Confederate ram CSS Atlanta and the Passaic-class ironclad monitors USS Weehawken and USS Nahant, which took place on 17 June 1863 in Wassaw Sound, a bay in the present day state of Georgia. Atlanta ran aground while attempting to break the Union blockade, and after a short battle surrendered to the Union forces. Captain Rodgers became a national hero, and he was promoted to Commodore and received the Thanks of Congress as a result of his decisive victory.
